Froth floatation | PPT
Introduction Floatation is an extractive process where various minerals can be selectively extracted. Flotation is a selective process and can be used to achieve specific separations from complex ores. For example, in poly-metal ores such as Pb-Zn- Cu, floatation allows separate extraction of Pb, Cu and Zn.

By referring to the tables "Minerals and Their Characteristics" (pages 332-339) it is seen that the perfect grade of a copper concentrate will be 63.3% when the copper is in the form of bornite, 79.8% when in the mineral chalcocite, and 34.6% when in the mineral chalcopyrite. A common association is that of chalcopyrite and galena.
